This invention lrelates toshoe-pressingmachinessuchfas are'nsed, forexample, to apply shaping pressure to the outsoles of shoes on theirlasts, this application being,zin part, a continuation of my copending'application' Serial No. 82,029., filed on January 18, 1926.

i that :cop'ending application thereis dis closed :a method ofshaping-or leveling outsoles by difierent treatment at-the forepart andtheshank respectively, the forep art being leveled .by rolling'pressureand the shank by pressure :applied to 'all portionsfthereofsubstantiallyzsinrultaneously. As therein ex planted, the use ofpressure of that character applied in the-shank portion of the shoe bymeans of a suitably shaped pressing member or pad is especiallyadvantageous in the V mmufacture of Womens-shoes of a type in the shankare thin and-are which the'transverse shank curvature of theshoefzbot-tom is comparatively great and in which the-edges offi'thesoleat the sides of against the upper.

' ob'ect of 'the'present invention is to providegeffective means forthus shapingthe shank sport-ion .of the sole, the term shankbeingusedherein to include-a portion sometimes Ieferredto as the Waist;In womens shoes -ithere 1s usually a pronounced upward slope of the.shoe bottom at the rear of the ball-line, and iniview of that conditionthe.

invention ,provides a novel organization including means for applyingsole-shaping pressure to the shank in adi-rection inclinedforwardlygtoward the 'forepart of ithe shoe respect to the direction ofthe height of the shoe, so that thepressureon portions of the sole:immediatelyatthe rear of the balls line will be especially effective toimpart to the sole the desired transverse curvature and to pressfitsopposite edges close to the upper. The invention is herein illustratedin its applicationsto a type 'ofmachine shown and described in LettersPatent No. 1,549,243, grantedknpon my application on August '11, 1925,that type of machine comprising a jack which engages the last or shoe atthe heel end andforwardly-of'theheel end to support-the shoe againstupward pressure .on itsbottom' '50 face, and a sole-pressing member-orpad.

Machines of the yp mted in the La;

ters .Patent mentioned are twin machines, compris ng. duplicate -mecl ianisms whereby one shoe is subJeCted to pressure simultaneously withtherelease from. pressure of another shoe previously ope-rated upon.Only' one of such mechanisms is herein illustrated or need be referredto for an understanding of the present invention. "As shown in Fig.1'

1, and as more fully illustrated and described in said Letters Patent,the machine is provided with a pair of vertical rods 10 on which thereis adjustably secured acasting 12 which serves'as a support fordownwardly extending arms 14 and 16 of a shoe-supporting jack, the'arm14 having thereon at its lower end a pin 18 for engaging the heel end ofthe last in its spindle hole, and the arm 16, as herein illustrated,being'provided for purposes Of the present invention with means morepar-' ticularly hereinafter described for supporting other portions ofthe shoe-and last against the pressure applied onthe sole. Mounted forverticaljfsliding movement on the rods 10 is a carrier 20 provided withmeans at its opposite sides for supporting apair of trunnions 22 fast ona pad b0): 24 on which is mounted apad 26 for applying pressure to thebottom of the shoe; The meansfor imparting operativemovement to thecarrier 20 is not shown in detail, but is fully illustrated anddescribed in the'above-mentioned Letters Patent. It will be understoodthat the shoe ismo'unted on the jack bytheoperator when the' carrier 20andthe pad 26 are in their lowermost positions, and that in theoperation of the machine the pad is moved upwardly to apply pressure tothe shoe, after which the machinecomes to rest, and that in the.neXt'ope-ration of the machine the shoe is released by downward movement:of the. pad simultaneouslywithrthe; application v ofpressureto ashoe bythejother twinmech anism. a, V w V For purposes :en 'agin g pin 18 onthe arm'l l ispositioned 1 3 t i inventi th i 1 S at such a heightrelatively to the shoe-engaging means on the arm 16 ithatthe shoe ispresented at a substantial inclination to the direction ofupwardmovement of the pad 26, with the forepart of the shoe upwardlyinclined, so that the pressure of the pad 26 on the shank portion of thesole is applied in a-direction inclined forwardly toward the forepartofthe shoe, the arrangement thus being suchthat in operating on ,shoesofa style in] which thereis'a comparatively sharp upward inclination ofthe sole'fiom'the ballline toward theheel-seat the 'pressure isapplied'to portions of the sole at the rear of the ball-line-in ageneral direction substan :tially perpendicular to the direction of suchupward inclination of the sole. As herein illustrated, the pad 26is'soformed thatit is limited substantially to engagement with the shankportion of the sole, and'asindicated at 28 in Fig. 5, moreover, the padis shaped to accentuate the pressure on the opposite side'portions ofthe sole and thereby insure that the 'edgesf'of the sole willbepressedclosely against the upper. (See Fig. 3.) The V pad is preferably soformed that at each end of its shank engaging portion. it presents a anyslight-engagement of the pad'with por s'oleis concerned. The 'pad box 24provides ELIlgld. support 'tionsof thesole located eitherforwardlyorrearwardly of the shank portion will have no; effect as far-asaltering the contour of'the i for the pad' and is free to'swing on thecar rier 20 by means of its trunnions 22, so that the pad may adaptitself to the inclination o'fthe shoe. The rear end of the pad, moreover, is somewhat heavier than the front end, so that-the pad box andthe pad will assumean inclination approximately corresponding to theinclination of the shoe even when the par'tsof the machine 2116111 theiridle positions' The pad is preferably'formed of rub-Q ber. and may, ifdesired, have. acovering of leather on its shoe-engaging face, as shown.

pressure of the shoe'on the padtends tomaintain'it in engagement--withthe abut ment 3O.

Forisupporting' the shoe against the pressure on the sole, the arm'16 ofthe jack is er:- tended for a*considerable 'distzmce lengthwise of theshoe and is so formed as to provide an abutment fora molded rubber pad38 arrangedto engage'the top of the shoe or last continuously from thehollow. at theback of the toe substantially to the rear'end ofthe instepportion of the la 'st,the arm and the pad having a contourlengthwise ofthe shoe 90 substantially fiat facetoward the sole, sothat' such as toconform substantially'to'the. contour ofthe'last in the location wherethe shoe orlast'is-engaged by'the' pad'r A firm support is thus providedfor the last in llne with the pressure applied to the shank. by the pad26 so as to insure against breaking the last un der the "heavysoleshaping pressure, esp-e} cially if the last'is a hingel'ast.Preferably 'the front end of the pad38 will beturned up awayfrom theshoe, as shown, toinsure against marking the shoe. IThe pad ispreferably so formed that its shoe-engagmg face is straight'widthwise ofthe shoe so that the same pad may be usedforboth right and left shoes.The .pad is mounted on the arm 16 between downwardly projecting flanges40 and 42 at the opposite sides of the arm, and is so formed as toextendlaterally under the edges of the flanges to avoid any possibilityof'contact of the metal arm 16 with the shoe. For 'holdi'ng'thepad inosition it is so molded as to 1 rovide ro- 7 jjections or lugs 44 on itssides which are received in openings formed" in the flanges 40. i and42' The flange 42-is detachable, as'illustrated particularly in Fig. 3,to permitconvenientreplacement of the pad when re-, quired; I The-heelpin 18 is supportedona holder 46 which is pivotally mounted at 48 on thearm 14, and the holder 46 is controlled by a spring 50 which tends totip the pin 18 in a forward direction, as common heretofore. It will beunderstood that when the last is I mounted on the pin 18 the pri 3 itslower end of: which is secured a member 56 r 14 and 16 to turn ab'eutaxes extending widthprovided on its .opposite sides with armsconnectedirespectively by'links 58 to the arms and 16, substantially asheretofore, :only 1 one of the links58 beingshown in the draw-- ings;By. this means the arms 14and" 16 are so connectedto each otheras'toconstrain thernto move" either toward or from each other in unison. Themach-ine is further pro vided with means for adjusting these arms towardor from-each otherto accommodate the ack to-shoes of differentlengths..' .For this purpose there isTprovided a screw 60.,

having right andIleft-hand threads thereon for engagement withcorresponding threads formed in" cylindrical: members 62 whichareswivel'ed in bearings'formedinthe arm's wise of the shoe. 'Byturningthersc'rewEGQ the arms may thusbe moved toward or from each other- It isdesirable that after the arms have thus been adjusted for any particularsize of shoe, they shall beheld rigidly against relative displacement inresponse to the pressure applied to theshoe. There isaccordingly'provided means forlengaging thescrew 60 frictionally toaiford increased,

insurance against accidental turning movement; For this'purpose each ofthe members 62 is provided with a threade'dbore formed axiallythereof,in which is mounted a small block 64 for engaging the screw 60frictionally and also a spring 66 which presses the block against thescrew andthe tension of; which is adjustable by means of ascrew 68;

It will be understood that the pressure of the blocks64 against thescrew 60'does not interfere with turning of the screw when it isrequired to adjust the jack, but 1 aifords sub-v stantial insuranceagainsttur'ning of lithe screw accidentally, forexample in response tothe pressure to which the jack is subjected in the operation of themachine on a shoe.

The manner of operation of the .maohine,

including that of the novel features provided by the present invention,has'been sufliciently described in connection with the description ofthe construction andrequires no. further explanation.

It is to be understood that whilethe invention is herein. illustratedin" its application to a machine of the type shown in the prior LettersPatent hereinbefore mentioned, in its more general aspects it is notlimited to machines of that particular type; and, further- .more,that'as to various novel details of construction disclosed, theinvention is not limited to machines for shaping soles or for applyingpressuret'o the shank the shoebottom exclusively.
